Rivers or lakes?
Stealth or distance?
Romance or efficiency?
Windy or calm?
Mostly dry flys or wet?
Tenkara is very effective for upstream euro nymphing or swinging wets, but a challenge on still water.
With 25' of "reach" stealth becomes critical.
Aside from hatches, I typically out fish traditional. (But I'm still learning, so we'll see...)
Tenkara in a wind (>10) is difficult. You are casting "leader" not heavy fly line.
Drys in the foam are fun. Drys in the film becomes a challenge due to proximity.
Spend a $200 and see if you like it. You can get by will less, but as an experienced fisher, you will appreciate a good rod.
